(1) Inductance is measured with a LCR meter 4284A(Agilent (1) LCR4284A (Agilent)100kHz
Technologies) or equivalent. Test frequency at 100kHz
(2) DC resistance is measured with 34420A (Agilent Technologies) or (2) 34420AAgilent3541(HIOKI)
3541(HIOKI). (Reference ambient temperature 25C) 25C
(3) Maximum allowable DC current is that which causes a 30 % (3)
inductance reduction from the initial value, or coil temperature to 30%40C
rise by 40C, whichever is smaller. 20C
